The EFL could take out an injunction to force Millwall into allowing Sky Sports to televise their clash with Watford this month, as the row between the club and the broadcaster escalated on Tuesday.
As Sportsmail revealed on Monday, Millwall want to block Sky from broadcasting Watford's visit to the Den on December 29 due to unhappiness at their coverage of last week's game against Queens Park Rangers, which was overshadowed by the racism row that erupted after the club's previous fixture against Derby.
The EFL's view is that Millwall must respect the League's £119million-a-year contract with Sky by admitting their cameras into the ground and they are seeking an amicable solution, but failed to make progress in talks with both parties on Tuesday.
